| Abstract: | For a finite spin chain, a functional representation of the generating function of the XY-model at nonzero temperature is obtained. Bibliography: 16 titles. Dedicated to the memory of V. N. Popov Translated fromZapiski Nauchnykh Seminarov POMI, Vol. 224, 1995, pp. 192–207. Translated by V. S. Kapitonov. |
